My Mom, Grandma and I All Swear by the Same Easy 200-Year-Old Lemon Posset Recipe
Sometimes, a few ingredients and a simple recipe can create the most picture-worthy dessert. That's what I've found with my family's 200-year-old lemon posset recipe.
This classic British dessert uses just four ingredients and the hollowed-out lemon as a vessel for serving. After mixing together sugar, heavy cream and lemons, and a pinch of salt, the refrigerator does the rest of the work as the treat chills and can be ready to serve for dinner in a few hours or brunch tomorrow.
My grandma always simply referred to this deliciously simple lemon dessert as "chilled stuffed lemons." The end result is similar to a panna cotta, but made without eggs or gelatin.
Because these are ingredients many of us usually have in our kitchens, you can easily put this together for a last-minute menu addition during your week. It's simple enough to not require too much planning ahead of time, and elevated enough where it can make an otherwise-ordinary meal feel extra fancy.
Craving the sweetness already? Me too. Here's how to make the no-bake dessert yourself-including some of my family's go-to tips and substitutions, like utilizing herbs and flavored salt, and the perfect garnish that makes the lemon posset even better.

What Makes My Family's Favorite 200-Year-Old Lemon Posset Recipe Different
Our family recipe uses heavy cream, sugar and lemon juice, and a pinch of salt-bringing it to a boil in a pan and simmering for just three minutes to deliver a creamy, lemony mixture every time.
The acidity of the lemon juice firms up the texture of the heavy cream as it heats, causing the mixture to thicken and the high fat content keeps the cream from becoming curdled. (If your mixture does curdle, resulting in a grainy texture, it can be strained to smooth it out before chilling.)
The addition of salt in this short ingredient list is important. If you have never used salt in a recipe for something sweet, give it a try when making desserts as it helps balance the sweetness of the sugar with the other ingredients. Flavored salts also work here with a lemon salt or a lavender version (which perks up many of my other dessert recipes).
Real lemon juice is the key to getting the right balance of a zing of citrus. My family has also made this with lime or blood orange juice for a fun twist on citrus ingredients.

Ingredients Needed
- 1 cup heavy cream
- ¼ cup sugar
- ¼ cup fresh lemon juice
- Pinch of salt
How To Make My Family's Lemon Posset Recipe
First, cut the lemons in half and squeeze for juice.
Don't skimp on the lemon juice used in this recipe as the tart lemon flavor is the star of the show here. Bottled lemon juice has a muted taste that won't help the citrus shine. (If your lemons feel like they are too firm and won't give off all their juices, roll the lemons back and forth under the weight of your palm on the kitchen counter a few times to help loosen up all the lemon goodness inside.)

Hollow out the lemons and remove any seeds.
Heat the cream, fresh lemon juice, sugar and salt.
Bring the cream mixture to a boil and lower to a steady, gentle simmer for three minutes. Keep a watch on the time as the three-minute mark is important for helping the mixture thicken.
Allow it to cool for 10 minutes.
Then, strain the mixture through a mesh strainer. This ensures a smooth consistency and removes any lumps that may have formed.
Pour into a vessel to chill and serve. Use a small glass, wine glass, ramekins or lemons sliced in half and hollowed out.
Refrigerate and chill for at least four hours or overnight.

Tips and Substitutions
After making this for years, here are a few of my tried-and-true tips, as well as some substitution ideas.
- Be sure to use a full fat heavy cream
- Only fresh lemon juice will do for the most concentrated lemon flavor
- Try a flavored salt like lemon or lavender
- Chill for at least four hours to get a consistent set up of the ingredients or overnight
- Substitute blood orange or lime for the lemon juice
- Infuse cream with vanilla beans or herbs like lemon thyme, rosemary, basil or mint
- Serve with shortbread or other type of cookie
- Serve with macerated berries and lemon zest
- Garnish with fresh mint and sanding sugar for a sweet crunchy texture on top

Lemon Posset Recipe Review: Final Thoughts
Whether you are making a large holiday dinner or planning a last-minute menu for a gathering, any recipes that can be made ahead of time with just a few ingredients are always a big help. And this is one of my go-tos.
This lemon posset can be assembled and chilled as you take care of other dinner items-and you can even use the lemons themselves as the vessel for serving or dress up the lemon posset and serve in a wine glass.
When a recipe calls for heavy cream, I often like to swap in a lighter cream but this recipe, with only a few ingredients, needs the fat in the heavy cream for texture to work with the acidity of the citrus.
Whole milk, half and half or low-fat milk will tend to clump and give a grainy and unpleasant consistency to the filling. The step of straining the mixture before chilling can help solve any problems with tiny bits before chilling and keep the mixture smooth.
With the fool-proof method of timing the three-minute simmer of lemon juice and cream, and a strainer to give a smooth texture to the filling, this recipe is easy to make, easy to love and easy to clean up!
